2.MDI, 4,4'difenilmetan diizosiyanat (saf MDI) i\u00e7in genel bir isimdir, belirli oranda saf MDI ve polifenilpolimetilen poliizosiyanat (polimerize MDI) i\u00e7eren bir kar\u0131\u015f\u0131md\u0131r ve saf MDI ve polimerize MDI'nin modifiye edilmi\u015f \u00fcr\u00fcnleridir. , poli\u00fcretan \u00fcretimi i\u00e7in en \u00f6nemli hammaddedir. Poli\u00fcretan\u0131n yan\u0131 s\u0131ra di\u011fer y\u00f6nlerde de az miktarda MDI kullan\u0131l\u0131r. Poli\u00fcretan, kau\u00e7u\u011fun elastikiyetine, plasti\u011fin mukavemetine ve m\u00fckemmel i\u015fleme \u00f6zelliklerine sahiptir, \u00f6zellikle \u0131s\u0131 yal\u0131t\u0131m\u0131, ses yal\u0131t\u0131m\u0131, a\u015f\u0131nma direnci, ya\u011f direnci, elastikiyet vb. a\u00e7\u0131s\u0131ndan. Di\u011fer sentetik malzemelerin e\u015fle\u015femeyece\u011fi avantajlara sahiptir. Etilen, polipropilen, polistiren ve ABS'den sonra alt\u0131nc\u0131 en b\u00fcy\u00fck plastik (\u015fimdi ABS'yi ge\u00e7erek be\u015finci en b\u00fcy\u00fck plastik haline gelmi\u015ftir), ulusal savunma, havac\u0131l\u0131k, hafif sanayi, kimya sanayi, petrol, tekstil, ula\u015f\u0131m, otomobil, t\u0131bbi vb. alanlarda yayg\u0131n olarak kullan\u0131lm\u0131\u015f, ekonomik kalk\u0131nma ve insanlar\u0131n ya\u015famlar\u0131 i\u00e7in vazge\u00e7ilmez bir ortaya \u00e7\u0131kan malzeme haline gelmi\u015ftir.
\nMDI ve TDI birbirlerinin yerine ge\u00e7er ve ikisi de poli\u00fcretan \u00fcretimi i\u00e7in ham maddelerdir. MDI'nin fiyat\u0131 biraz daha d\u00fc\u015f\u00fckt\u00fcr ve toksisitesi TDI'den daha d\u00fc\u015f\u00fckt\u00fcr. Ancak k\u00f6p\u00fck \u00fcretirken yo\u011funluk TDI sisteminden daha y\u00fcksektir. MDI ile olu\u015fturulan poli\u00fcretan \u00fcr\u00fcnlerinin kal\u0131planabilirli\u011fi nispeten iyidir.<\/p>\n
